Abstract: 1,142,765. Methyl adamantanes; bicycloheptanes. SUN OIL CO. 21 March, 1967 [8 April, 1966], No. 13191/67. Heading C5E. C 11-12  methyl-substituted adamantanes having at least one non-bridgehead methyl substituent are prepared by (a) contacting a C 11-12  tricyclic naphthene having at least two of the rings joined to each other by 1,3 or 1,4 fusion at -10‹ to 100‹ C. with an AlCl 3 /HCl, AlBr 3 /HBr or HF/BF3 catalyst to effect isomerization and produce methyl-substituted adamantane; (b) stopping the isomerization at a stage where non-bridgehead methyl-substituted adamantane is the main isomerization product and, in the C 12  case, before substantial appearance of 1,3- dimethyladamantane; and (c) recovering the desired product. In the case of C 12  starting materials the dimethyladamantane product may comprise singly and/or doubly non-bridgehead isomers. Suitable catalysts are preformed liquid complexes obtained by reacting AlCl 3  or AlBr 3  and HCI or HBr, respectively, with a paraffinic hydrocarbon of at least 7 carbon atoms (preferably such complexes contain free AlCl 3  or AlBr 3  and are used in the presence of gaseous HCI or HBr); and a combination of HF, BF 3  and an initiator which is water or a C 1-5  olefin, alcohol, ether or alkyl halide. Suitable starting materials are specified, those used in the examples being (1) a mixture of methyl trimethylene (2.2.1) bicycloheptane isomers, prepared by codimerization of cyclopentadiene and methyl cyclopentadiene followed by hydrogenation, and (2) a mixture of dimethyl trimethylene (2.2.1) bicycloheptane isomers, prepared by dimerization of methylcyclopentadiene followed by hydrogenation.

Abstract: 284,304. Compagnie pour la Fabrication des Compteurs et Materiel d'Usines Ó Gaz. Jan. 29, 1927, [Convenvention date]. Drawings to Specification. Cut-out arrangement.-In the selective relays of Specification 258,570, in which the time taken for the relay to close is a function of the square of the positive phase sequence voltage less the square of the residual component of the voltages a couple proportional to the first two of these quantities is obtained by supplying the magnet system with two windings directly fed by two voltages, star or delta, of the system of threephase voltages. A star and a delta voltage may be used. The protection is incomplete if the residual component is not taken into account but may be made complete by the use of two relays each fed by two star or delta voltages or by a suitable star and delta. voltage. Alternatively, two electromagnets driving a single movable train may be used instead of two relays.

Patent GB-134597-A (GB)
IPC: A63B69/40
Abstract: 134,597. Brice, H. Nov. 1, 1918. Projecting-appliances.-A multiple ball-throwing device comprises the hopper a from which a ball is directed to each of the radially inclined tubes g within the casing c, where it is expelled by the release of a spring-pressed plunger k. The simultaneous release of the plungers and the consequent expulsion of the ball from each tube is effected by the withdrawal of a catch-plate w which has secured, against the pull of the spring r, the linkages controlling the plungers. In playing a game, the balls, which are cast in different directions, are caught and dealt with by the players, for instance by being returned to the hopper. The balls may be caught in nets secured to handles. To set the plungers k in their striking position, the pedal u is provided, which, on depression, carries down the guided sleeve p against the action of the spring r and at the same time retracts the plungers. Suitable guides in the casing below the hopper convey the balls singly to the plunger tubes g. The apparatus may bo mounted so as to vary the direction in which the balls are cast. The pedal u and the releasing-mechanism may be operated from a distance.

[Classes 29 and 64 (iii)] Compressed air or vapour is supplied to a tube, preferably of helical or sinuous form, having a bore adapted to impede the flow of the air &c. and thereby create friction, the heat induced being removed by an external cooling medium so that thereafter the air &c. expands to cool it to a low temperature. The tube may have a hollow projection 170 extending parallel to the axis of the helix, Fig. 3, or at right-angles thereto, Fig. 4, this projection being surrounded by a cooling jacket 190, the friction being developed mainly in the projecting portion. The tube may be of gradually increasing cross-sectional area as shown. The tube may have a sinuous wavy form, and may be of star or elliptical cross-section, or of the cross-section shown in Fig. 13. The apparatus may be used in air liquefying processes, the cooled air from a primary coil being used as a cooling medium in the jacket of a secondary coil and so on. Where water is used as cooling medium it may become warmed to produce a supply of hot water.

Abstract: 1,096,068. Resiliently mounted seats. DEERE & CO. March 28, 1966 [March 29, 1965], No. 13555/66. Heading A4U. In a tractor seat, in which links 36 and 38 can be tilted rearwardly to carry the seat into and out of use position, vertical springing is provided by a compression spring unit 34 acting on a cross-bar 52 of rear links 38. Catch 74 retains the seat in the position of use and, on being pivoted upwardly, to release projection 68, allows the seat to be lifted upwardly and rearwardly, about pivots 40 and 42. This movement relieves the bar 52 of the pressure of the coil spring in unit 34, which is transmitted through links 50. Continued rearward rotation of the links 36, 38 removes links 50 from contact with bar 52 (Fig. 3, not shown). The resilience of the mounting may be varied by altering the position of blocks 60 along slots 54.

Title: Synchronising electronic time bases
Inventor: FAIRHURST HAROLD ALFRED
IPC: H04N5/12
Filed: 1953-05-14
Abstract: 750,162. Automatic frequency control. MURPHY RADIO, Ltd. May 14, 1954 [May 14, 1953], No. 13579/53. Class 38 (4). The frequency of a time-base scanning- oscillator is controlled by the integrated output of a valve, to two electrodes of which are applied respectively, in opposite polarity, synchronizing pulses and pulses derived from the time-base circuit, the valve being conductive only when both pulses are present and not simultaneously present. In one embodiment a television line scan generator 7, Fig. 1, is coupled by means of coil 1 to the anode of a gate valve 4 so as to apply a positive potential during the line scan and a negative pulse during the fly-back. Positive sync. pulses are supplied through the delay circuit 10 to the grid of valve 4 so that the valve conducts according to the extent by which the sync. pulses fail to overlap the flyback pulses. The anode current of valve 4 through the smoothing circuit 5, 6 produces the frequency-controlling bias for the generator 7. The valve 4 may also act as the sync. separator of the television receiver by biasing it from a diode rectifier supplied with the signals, Fig. 2 (not shown). To eliminate the effects of the frame sync. pulses on the output of the gate valve 4, a further gate valve 17, Fig. 3, is provided. Positive sync. pulses are fed to the grids of valves 4 and 17, and a positive pulse is applied to the anode of 17 during line scan fly-back from coil 18, so that the valve conducts, when time base and sync. pulses coincide to produce a positive going pulse across the cathode resistor 19 thus cutting off valve 4. Valve 17 is allowed to conduct slightly during framing pulses by the presence of potentiometer 21. The correcting bias is taken from load 5 and the smoothing network 22-25. In another embodiment, differentiated pulses are employed to reduce the effect of the frame sync. pulses, the sync. separator valve 26, Fig. 4, being used to feed the pulses to the grid of the gate valve 30 through a differentiating circuit 27, 28 and the phase inverter 29. The controlling voltage is smoothed by circuit 33, 34, 36, 37 and taken from the anode of the D.C. amplifier 35. In a circuit using undifferentiated negative sync. pulses applied to the grid of valve 47, Fig. 7, positive pulses derived from the line scan transformer coil 48 are applied to the anode. The controlling voltage appears across resistor 49 and is smoothed by the filter 51-54.
